A good friend once told me that we should never make decisions based on fear of the alternative. That is to say, instead of weighing your future on the scale of security, why not choose that which frightens you a little. Like swinging on a trapeze, there is a terrible-wonderful moment when you have to let go and free-fall your way to the next grab. But the more times you find the new bar there to meet you, the stronger your trust in the unknown grows.
